Costcodle is a free daily puzzle that gives you one Costco product and asks you to guess its price in US dollars. You have six attempts, and each guess tells you to go higher or lower. When you are within 25% of the price it says Close, and within 5% you win. The game resets every day at 00:00 UTC with a new item.
The game is designed for anyone who enjoys quick daily challenges like Wordle but prefers a numbers-based guess. It works in any modern browser on phone or desktop, and no account is needed because your progress and stats are saved on your device. You can share your result as a row of emoji without giving away the price, so friends can still play the same puzzle.
Notable features include Unlimited mode that offers random past items to play back-to-back, a Chrome browser extension that puts the daily puzzle in your toolbar, and a spoiler-free sharing format. Prices are snapshots from the original game, not live store prices, and the project is an independent fan creation not affiliated with Costco.
